Some jokes....please explain them to me...?

Ok Jokes aside, but I seriously could not understand these jokes. Laugh/smile but after that please explain each one to me. Thanks.

Two nuns are riding bicycles down a cobblestone street. The first says "I've never come this way before", to which the other replies, "must be the cobblestones".

What's the difference between a preacher at his pulpit and a woman in the tub?

A: The preacher's soul is full of hope.

A Helen Keller joke:

Ques: Why did nobody hear her?

Ans : She was wearing mittens.

Ques: Severus Snape has an erection, and he runs right into a brick wall. What does he say?

Ans: "Ow, My nose!

Two ethnics are out duck hunting. They hunt and hunt and hunt and still have not killed one duck. Finally, ethnic #1 says to ethnic #2, 'Maybe we'd do better if we threw the dog up higher.

"Husseinfeld"

"Matima Loves Chachi"

Some jokes....please explain them to me...?-Myspace pictures

1- The second nun thinks the first nuns means she came sexually from the bumping and shaking from the sobble stone

2-??

3- Helen talks with her hands so she is not "heard" when you can not see her hands

4- It means Severus Snape has a small penis that does not stick out futher than his nose hence why he hurts his nose rather than is erection

5- Silly honestly but that the ethnics do not see or understand the purpose of the dog and are throwing them in the air rather than getting the dog to fetch the shot ducks

6-??

7- The beeper would be lost in the rolls of fat and then then she could not feel the pager or hear it so needs someyhing huge .

i think you stay in school and not go for comedy as a career.
What do you get when you cross a Shitzu and a Bulldog?

A Bullshit! hahahhaha

oh what about this one...

This guy asks a question on Y Answers, but nobody answers him for real. They just start telling jokes and he gets mad. What does he do then?

Nothing. hahahahah

The mama so fat one is because she's so big, that when she wears a VCR it looks small like a beeper.
well sevrus snape has a big nose ethnics are thorwing a dog at the ducks when they should be using a GUN momma is so fat cause the beeper absorbs into the fat so she cant hear it or see it so she needs something as big as a vcr to see it
whoever made those jokes should be shot, they were hopeless
lol lol lol lol lol
OK I'll help you out with the third one about Helen Keller but I suspect that you are too young to appreciate the humor in the others. Helen Keller was deaf, and blind, and so could only communicate with her hands (until she learned to speak) and so if she were wearing mittens that would somehow prevent her from being 'heard'.
I only know some of them. Hellen does sign language, she can't "talk" with mittens. The ethnics are stupid. You know how dogs fetch the ducks when they fall after you shoot them?
the nuns change come to *** #2 hole full of soap!#3 no one could see her talking #4 ya got me??#5 they were throwing dog in air to try %26amp; grab ducks flyin by!!#6 is just pure stupid There ya have it now WAKE UP!! are you blonde?
